7 MITIGATION MONITORING AND REPORTING PROGRAM In accordance with the California Environmental Quality Act (CEQA), Sacramento Area Flood Control Agency (SAFCA) prepared an Initial Study/Proposed Mitigated Negative Declaration (IS/MND) to provide the public and responsible and trustee agencies with information about the potential environmental effects associated with the construction and operation of the Site 18A Culvert Replacement and Fish Passage Enhancement Project (hereafter referred to as the proposed project ). The IS/MND concludes that implementation of the proposed project would generate significant and potentially significant adverse environmental impacts. For all potential impacts, the IS/MND prescribes feasible mitigation capable of reducing these impacts to less-than-significant levels. Section of the California Public Resources Code and California Code of Regulations (CCR) Sections 15091(d) and of the State CEQA Guidelines, require a public agency to adopt a reporting and monitoring program for changes to the project that it has adopted and incorporated into the project, at the time of approval, to mitigate, avoid, or reduce significant effects on the physical environment. These conditions are also referred to as mitigation measures. The Mitigation Monitoring and Reporting Program is to be used by SAFCA to ensure that adopted mitigation measures identified in the IS/MND are implemented and that their implementation is documented. The Mitigation Monitoring and Reporting Program is presented in tabular format. The table columns contain the following information: Mitigation Number: Lists the mitigation measures by number, as designated in the IS/MND. Mitigation Measure: Provides the text of the mitigation measures, each of which has been adopted and incorporated into the project. Timing/Schedule: Lists the time frame in which the mitigation measure is expected to take place. Implementation Responsibility: Identifies the entity responsible for complying with the requirements of the mitigation measure. Completion of Implementation: SAFCA is responsible for reporting on implementation of the mitigation measures. The Action column is to be used by SAFCA to describe the action(s) taken to complete implementation. The Date Completed column is to be used by SAFCA to indicate when implementation of the mitigation measure has been completed. SAFCA, at its discretion, may delegate implementation responsibility or portions thereof to qualified consultants or contractors.

SAFCA shall implement the following measures to avoid and minimize adverse impacts to woolly rose-mallow. a) Before construction activities begin, a focused survey will be conducted by a qualified botanist for woolly rose-mallow shrubs that may be present in or within 50 feet of areas where ground disturbance would occur. To the extent feasible, depending on timing of project implementation, surveys will be conducted during the blooming period for this species (June September). b) If woolly rose-mallow is detected, areas where the species occurs will be fenced for complete avoidance during project implementation, to the extent feasible. c) If woolly rose-mallow is present in areas where disturbance cannot be avoided, a qualified botanist will assess the feasibility of salvaging and transplanting individuals as part of the revegetation component of the project. If such actions are deemed feasible, they will be implemented under the direction of a qualified botanist and in coordination with California Department of Fish and Wildlife (CDFW). Avoid and Minimize Disturbance of Special-status Fish in Natomas East Main Drainage Canal (NEMDC)/Steelhead Creek. SAFCA shall implement the following measures to avoid and minimize disturbance to special-status fish in NEMDC/Steelhead Creek. a) No grading work within the existing floodway will occur during the designated flood season (i.e., November 1 to April 15), and work will not begin until evaluation of upstream conditions indicate that inundation of the construction area is unlikely to occur. b) A worker awareness training program will be conducted for construction crews before the start of construction activities and as needed when new personnel begin work on the project. The program will include a brief overview of sensitive fisheries and aquatic resources (including riparian habitat to be preserved) on the project site, measures to minimize impacts on those resources, and conditions of relevant regulatory permits. Timing/Schedule Before construction activities begin and during revegetation. Before, during, and as needed after construction activities.

Sensitive habitat information will be incorporated into project bid specifications, along with a requirement for contractors to avoid these areas. Conduct Pre-construction Surveys and Minimize Disturbance and Potential Loss of Active Nests of Special-Status Birds. a) SAFCA shall implement the following measures to minimize disturbance and potential loss of active nests of special-status birds. b) Focused surveys for Swainson s hawk and other nesting raptors will be conducted by a qualified biologist before on-site project activities begin. To the extent feasible, surveys for Swainson s hawk will follow guidelines provided in Recommended Timing and Methodology for Swainson s Hawk Nesting Surveys in California s Central Valley (Swainson s Hawk Technical Advisory Committee 2000). A minimum of one survey will be conducted no more than 14 days before beginning project activities that are conducted during the nesting season (March 15 August 31). Surveys for Swainson s hawk nests will include all accessible areas of suitable nesting habitat located within 0.25 mile of areas subject to project disturbance, and surveys for other raptors will include accessible suitable nesting habitat within 500 feet of project disturbance. c) Surveys for Modesto song sparrow will include suitable habitat east of Northgate Boulevard and within up to 200 feet of areas of project disturbance, depending on the disturbance level. Surveys will be conducted within 7 days before on-site project activities begin in a given area during the migratory bird nesting season (March 1 August 31).

The appropriate size and shape of the buffers will be determined by a qualified biologist and may vary depending on the species, nest location, nest stage, and construction activity. The buffers may be adjusted if a qualified biologist determines that such an adjustment would not be likely to adversely affect the nest. Monitoring will be conducted to confirm that project activity is not resulting in detectable adverse effects on nesting birds or their young. No project activity will begin within the buffer areas until a qualified biologist has determined that the young have fledged or the nest site is otherwise no longer in use. Avoid and Minimize Disturbance of Riparian Vegetation and Develop Restoration Plan to Compensate for Tree Loss. SAFCA shall implement the following measures to avoid and minimize disturbance of riparian vegetation and trees. a) If canopy and/or root pruning, cabling, or other corrective measures for preserved trees are necessary, such measures will be conducted as specified by a Certified Arborist and will conform to the pruning standards of the International Society of Arboriculture. b) Ground disturbance activity, equipment, and vehicles will not encroach within 1 foot of the drip line of trees to be preserved, to the extent feasible. The dripline area will be protected with high visibility fencing or tape before any ground disturbance or movement or storage of heavy equipment and other vehicles occurs. All fencing/tape will be removed following construction and before revegetation plantings are installed. c) Excavating within a distance of half the drip line beyond the drip line will be avoided whenever practicable. If necessary, any authorized fill or excavation within this area will be supervised by a Certified Arborist. d) To prevent root tearing and mangling by heavy equipment, hand digging will be conducted around roots in the vicinity of major trees to be preserved before pruning of roots greater than 2-inch diameter. Severed roots larger than 2 inches in diameter will be pruned or trimmed and covered with earth as soon as possible.

Mulch and/or plywood will be removed after construction is complete. f) Removal of protected trees and other riparian vegetation (e.g., shrubs) will be compensated by planting appropriate species as part of the revegetation component of the project. Replacement plantings will be provided in accordance with City and County ordinances. Other riparian vegetation will be compensated at a 1:1 replacement ratio, based on the acreage removed. Revegetation efforts will be implemented as described in the restoration plan that has been prepared for the project. This will ensure adequate plantings of appropriate species are installed, maintained, and monitored to meet replacement requirements and compensate for removal of protected trees and other riparian vegetation. Geology and Soils GEO-1 Prepare and Implement a Grading and Erosion Control Plan. a) Before earthmoving activities commence, SAFCA shall prepare and implement a grading and erosion control plan. The grading and erosion control plan will be prepared and implemented before on-site grading activities begin. The plan will be consistent with the State s National Pollutant Discharge Elimination System permit, and will include sitespecific grading associated with culvert replacement and restoration activities. b) The aforementioned plan will include the location, implementation schedule, and maintenance schedule of all erosion and sediment control measures; a description of measures designed to control dust and stabilize disturbed soils within the construction-site; and a description of the location and methods of storage and disposal of construction materials. Erosion and sediment control measures could include the use of berms, straw cover, swales, wattles, and silt fencing, and covering or watering of stockpiled soils to reduce wind erosion.
